    DC-UbP/UBTD2 is a ubiquitin (Ub) domain-containing protein first identified from dendritic cells, and is implicated in ubiquitination pathway. The solution structure and backbone dynamics of the C-terminal Ub-like (UbL) domain were elucidated in our previous work. To further understand the biological function of DC-UbP, we then solved the solution structure of the N-terminal domain of DC-UbP (DC-UbP_N) and studied its Ub binding properties by NMR techniques. The results show that DC-UbP_N holds a novel structural fold and acts as a Ub-binding domain (UBD) but with low affinity. This implies that the DC-UbP protein, composing of a combination of both UbL and UBD domains, might play an important role in regulating protein ubiquitination and delivery of ubiquitinated substrates in eukaryotic cells.
